Birefringent optical films (10, 12, 14) have a Brewster angle (the angle at which reflectance of p-polarized light goes to zero) which is very large or is nonexistant. This allows for the construction of multilayer mirrors and polarizers whose reflectivity for p-polarized light decreases slowly with angle of incidence, are independent of angle of incidence, or increase with angle of incidence away from the normal. As a result, multilayer films (10) having high reflectivity (for both planes of polarization for any incident direction in the case of mirrors, and for the selected direction in the case of polarizers) over a wide bandwidth, can be achieved.

Avec les films optiques biréfringents (10, 12, 14), l'angle de Brewster (c'est-à-dire l'angle auquel le facteur de réflexion de la lumière polarisée p se dirige vers le zéro) est très grand, voire même inexistant. Ceci permet de fabriquer des miroirs ou des polariseurs multicouches dont la réflectivité de la lumière polarisée p diminue lentement en fonction de l'angle d'incidence, est indépendante de l'angle d'incidence, ou augmente lorsque l'angle d'incidence s'éloigne de la normale. On peut ainsi obtenir sur une vaste largeur de bande des films multicouche (10) à réflectivité élevée (sur les deux plans de polarisation et pour toute direction d'incidence dans le cas des miroirs; pour une direction d'incidence choisie dans le cas des polariseurs).
